Much of this evolution is related to a more comprehensive understanding of the behavior of hard and soft tissues post-extraction. The concept that implant placement at the time of extraction will maintain alveolar bone dimensions 1 has been refuted in animal and human studies. 2-4 This enhanced knowledge of physiologic modeling and remodeling has led to numerous strategies geared toward preserving 3-dimensional ridge morphology resulting in stability of esthetic outcomes. 5,6 Along with surgical methods of preservation and augmentation, prosthetic treatment plays a significant role in achieving and maintaining soft-tissue harmony. 7,8 Over time, patients treated in the developmental stages of im-plantology may need additional treatment. Teeth adjacent to implants may fail, requiring extraction and replacement with implants. Abstract: Over time, patients treated in developmental stages of implantology may need additional treatment, as teeth adjacent to implants may fail and require replacement themselves with new implants. Blending newer implant rehabilitations into a dentition with existing implant-supported restorations can be challenging. The use of implants with a subcrestal angle correction (SAC) enables predictable screw-retained anchorage of temporary and definitive restorations. An SAC implant often can be placed into the palatal bone of an extraction socket, along the incisal angle of the crown, allowing screw retention of the prosthesis. This case report demonstrates the use of both straight and SAC implants combined with hard-and soft-tissue augmentation and serial provisionalization to replace hopeless teeth adjacent to pre-existing implants and improve esthetics in the anterior maxilla.
